T400 not found on Lenovo support?

I'm trying to disable the bluetooth radio (but not the wifi) on a T400. 


the T400 does not appear on or


Fn-F5 does not respond.  Some other Fn combos do work like the keyboard light and the screen back light and numlock.


There is a radio power switch but it turns off both the wifi and bluetooth.


I've installed 3 different bluetooth drivers but non have a TURN IT OFF command.


XP sp3


bthprops.cpl is version 5.1.2600.5512 (4/14/2008)

Looks to be a Broadcom device.

The system/hardware device manager shows drivers installed and working.

no sign of any bluetooth options in the bios.


After several years of use, this T400 just started (today) with the messages to install blue tooth drivers.  Something must have triggered it to try.  The auto install failed so I downloaded drivers from the www and non allow me to turn it off.  Weird.
